Impressora 3D de Bolso? E fazer Plástico com Cola, um Fórmula-1 impresso em 3D, um Drone de Vigilância, e Gás, de Galhos!

Uma Impressora 3D de Bolso, com um Preço também pequeno, eis algo de louvável, para apoiar, e ter um em casa... Ou dois ou três, conforme os Filhos!

$99 palm-sized PocketMaker 3D printer launches on Indiegogo 
While 3D printers do honestly come in all shapes and sizes, the vast majority of models feature roughly the same desktop size – with size differences usually being negligible. While the dream is always to go bigger and wider to facilitate larger prints and more ambitious projects, there’s a lot to be said for downsizing as well. Aside from the obvious benefit of making your 3D printer extremely portable, it also means 3D printing smaller, more efficient objects and optimally using your build volume. Why be tempted to go bigger if smaller means becoming more efficient? If this sounds appealing, then the palm-sized PocketMaker might be something for you. 

Para além do Ooogoo, e do Sugru, podem fazer o vosso próprio Plástico, com Cola de Madeira e Talco, para peças ou moldes:

Making plastic with glue
This instructable is an experiment in making my own plastic using glue as the main binder material.
For this instructable you will need the following:
- PVA Glue
- Talc Powder (material to be bound)
- Mixing cup
- A harp inter-dental cleaner
- A Dremel multi
- A palette to spread samples on
- A spreader

E que tal, um modelo de carro de Fórmula 1, rádio-controlado, feito com a vossa Impressora 3D?
Cá está como o imprimirem, e montarem, e se também quizerem fazer a Electrónica, será adicionada, depois:

3D Printed 1:10 OpenRC Formula 1 car
Daniel Norée  
This is the OpenR/C Formula 1 car. It´s the third generation 3D printed OpenR/C car and this time around focus is on simplicity! You can print everything in PLA except the tires which are done in NinjaFlex! Of course you can print it in any material you like but for those that want to print a car but only have PLA at hand, this is the project for you!
This guide explains how to assemble the OpenRC F1 car. If you want to add electronics to make it radiocontrolled another step will be added later. 

Não há campo de actividade em que não se possa usar um Arduino, ou, neste caso, um Raspberry Pi!!!
Até para terem um Drone para vigiar as vossas Propriedades, Quintas, e Casas, ou sei lá, para brincarem com o Canito, do Escritório! 

Raspberry Pi Surveillance Rover (Land Drone)
Ever wanted to have a surveillance drone to monitor your surroundings? Of course you have!
Using a Raspberry Pi for the on-board logic, this compact, mobile computer, will create a local port that streams a video in real-time while simultaneously creating Bluetooth sockets to read values sent by a custom android app. The app syncs with the drone and uses user input to send instructions to the drone instantly. This project is fairly difficult to make from scratch, so hopefully the following will make life easier and provide some insight for drone enthusiasts like myself. All the software used for this project is provided. The code used was originally written by myself, but a few lines might have come from other sources. Feel free to modify and share the code to your liking. Please use the information provided responsibly and have fun! 

Gás que pode fazer funcionar um Motor, ou até mesmo um Automóvel, a partir de Galhos, e Serradura?
Já foi feito, em tempos de Guerra!
E pode ser uma boa maneira de se ter um Gerador, ou ainda melhor, um Aquecedor de àgua, que limpa o Quintal de folhas e galhos!

Power in the Apocalypse (How to build a Wood-Gasifier)
In this Instructable I will be showing you the steps I used to build my Wood/Biomass Gasifier. It was really a fun project and I would encourage anyone serious about preparedness to build one. Now in case you don't know what a Gasifier is (and don't feel bad if you don't as very few people do lol), they are quite simple, let me explain. Essentially all gasification is, is a form of incomplete combustion, heat from the burning solid fuel creates gases which are unable to burn completely because of the insufficient amounts of oxygen from the available supply of air, it then filters those gasses(which is by weight: 20% hydrogen, 20% carbon monoxide, 50 to 60% nitrogen, and a little bit of methane) And you can really use any kind of Biomass(organic material) that will burn. You can even use things like paper, coal, peat, and lignite. You can then use that filtered gas to run any thing from a generator to a car. So now that you have a basic understanding of what gasification is, lets get down to the build!!!
